Robertson was a 1976 graduate of The McCallie School. He graduated from Yale in 1980, and afterward graduated from his father's alma mater, Washington and Lee University, with a Juris Doctor degree. Following his graduation from W&L, Robertson practiced law in Norfolk, Virginia, for ten years. On a short-term mission trip to India, Gordon believes "[God] opened [his] heart to the plight of millions of unreached souls."[1] He responded by leaving his law firm and moving to the Philippines.[1]

In 1988, Gordon Robertson and his father, along with Dick Weinhold of the Texas Robertson campaign, and Billy McCormack, a Southern Baptist pastor in Shreveport, Louisiana, were named the four directors of the newly-organized Christian Coalition of America,[3] which continued to operate as a vehicle of the Religious Righat after Pat Robertson's failed bid for the Republican presidential nomination.

Robertson officially joined his father's CBN in 1994, when he founded CBN Asia, Inc., which included a weekly television show, The 700 Club Asia, with the goal of closely replicating the aspects of the original 700 Club to include the culture of the Philippines. He launched Operation Blessing Philippines and the Asian Center for Missions and facilitated the creation of CBN WorldReach centers in India, Indonesia, Thailand, Hong Kong and Beijing. Gordon returned to the USA in April 1999 to co-host the original 700 Club and, more recently, The 700 Club Interactive program which is seen on ABC Family and online. Currently he is producing the new CBN Superbook series which teaches children the truth of Christ in God's word.[1]

Today, Robertson is on CBN's board of directors. In addition to co-hosting The 700 Club, he is also an executive producer. He and his wife, Katharyn, live in Virginia with their three children.[1]
